I have a webpage with a WatchPosition call which works fine in regular browsers. However, the dialog for requesting GPS Permission never shows when the webpage is loaded from a WebView with WebChromeClient and onGeolocationPermissionsShowPrompt is never called.
public class GeoWebChromeClient extends WebChromeClient {
public void onGeolocationPermissionsShowPrompt(String origin, android.webkit.GeolocationPermissions.Callback callback) {
Log.d("geolocation permission", "permission >>>"+origin);
callback.invoke(origin, true, false);
}
}
public class GeoWebViewClient extends WebViewClient {
@Override
public void onReceivedSslError (WebView view, SslErrorHandler handler, SslError error) {
handler.proceed();
}
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// When user clicks a hyperlink, load in the existing WebView
view.loadUrl(url);
return true;
}
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView Browser = (WebView) findViewById(R.id.Browser);
WebSettings webSettings = Browser.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
webSettings.setAppCacheEnabled(true);
webSettings.setDomStorageEnabled(true);
webSettings.setGeolocationEnabled(true);
Browser.setWebViewClient(new GeoWebViewClient());
Browser.setWebChromeClient(new GeoWebChromeClient());
Browser.loadUrl("http://192.168.1.102/");
}

onGeolocationShowPrompt doesn't actually show a prompt itself, it is just a method that gets called when the page requests your Geolocation. You'll need to create your own prompt for the user like shown below (placed inside the onGeolocatioonShowPrompt method):
final boolean remember = true;
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Locations");
builder.setMessage(origin + " Would like to use your Current Location").setCancelable(true).setPositiveButton("Allow",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int id) {
// origin, allow, remember
callback.invoke(origin, true, remember);
}
})
.setNegativeButton("Don't Allow",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int id) {
// origin, allow, remember
callback.invoke(origin, false, remember);
}
});
AlertDialog alert = builder.create();
alert.show();
